The equal friction method for sizing air ducts is often preferred because it is quite easy to use. The method can be summarized to. Use the actual heat, cooling or air quality requirements for the rooms and calculate required air volume flow - q. Use 1 to summarize and accumulate total air volume flow - q total - in the system. Be aware that maximum load conditions almost never occurs in all rooms at the same time.

Ducts are conduits or passages used in heating, ventilation, and air conditioning HVAC to deliver and remove air. The needed airflows include, for example, supply air , return air , and exhaust air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort.
